Diphenyloxazoline derivatives

ABSTRACT

The invention relates to novel diphenyloxazoline derivatives of the formula (I) ##STR1## in which a) A represents tri- to pentasubstituted phenyl and 
     B represents substituted phenyl or 
     b) A represents mono- or disubstituted phenyl and 
     B represents at least trisubstituted phenyl, but where at least one substituent is not fluorine, chlorine, bromine, C 1  -C 6  -alkyl or -alkoxy, 
     to a number of processes for their preparation and to their use as pest control agents.

The invention relates to novel diphenyloxazoline derivatives, to a number of processes for their preparation and to their use for combating animal pests.

It is already known that certain oxazoline derivatives possess insecticidal and acaricidal properties (cf. e.g. EP-A 0 345 775 and EP-A 0 432 661). However, the activity of these previously known compounds does not give complete satisfaction in all areas of application, especially at low application rates and concentrations.

The novel diphenyloxazoline derivatives of the formula (I) have now been found ##STR2## in which a) A represents tri- to pentasubstituted phenyl and

B represents substituted phenyl or

b) A represents mono- or disubstituted phenyl and

B represents at least trisubstituted phenyl, but where at least one substituent is not fluorine, chlorine, bromine, C₁ -C₆ -alkyl or C₁ -C₆ -alkoxy.

It has also been found that diphenyloxazoline derivatives of the formula (I) are obtained by

α) reacting amino alcohols of the formula (II) ##STR3## in which B is as defined above

with a carboxylic acid of the formula (III)

    A--COOH                                                    (III)

in which

A is as defined above,

with a dehydrating agent, optionally in the presence of a diluent; or

β) reacting amido alcohols of the formula (IV) ##STR4## in which A and B are as defined above

with a dehydrating agent, optionally in the presence of a diluent; or

γ) reacting amide derivatives of the formula (V) ##STR5## in which A and B are as defined above; and

X represents a leaving group such as halogen, alkylsulfonyloxy or arylsulfonyloxy

with a base, optionally in the presence of a diluent.

It has also been found that diphenyloxazoline derivatives of the formula (I) are very highly suited to combating animal pests. They are distinguished in particular by high activity towards arthropods and nematodes.

Surprisingly, the diphenyloxazoline derivatives of the formula (I) according to the invention display a considerably improved activity towards animal pests than the previously known compounds which are closest in terms of constitution.

A general definition of the compounds according to the invention is given by the formula (I).

Example A

Tetranychus Test (OP resistant/dipping treatment)

Solvent: 7 parts by weight of dimethylformamide

Emulsifier: 1 part by weight of alkylaryl polyglycol ether

To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amount of solvent and the stated amount of emulsifier, and the concentrate is diluted with emulsifier-containing water to the desired concentrations.

Bean plants (Phaseolus vulgaris) which are heavily infested with all developmental stages of the red spider mite Tetranychus urticae are dipped in a preparation of the active compound of the desired concentration.

After the desired time, the action in percent is determined. 100% means that all the spider mites have been killed, 0% means that none of the spider mites have been killed.

In this test, for example the compounds from Preparation Examples 1, 2 and 5 exhibit a degree of mortality of 98% after 7 days, at an exemplary concentration of active compound of 0.01%.

Example B

Phaedon Larvae Test

Solvent: 3 parts by weight of dimethylformamide

Emulsifier: 1 part by weight of alkylaryl polyglycol ether

To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amount of solvent and the stated amount of emulsifier, and the concentrate is diluted with water to the desired concentration.

Cabbage leaves (Brassica oleracea) are treated by being dipped into the preparation of the active compound of the desired concentration and are infested with mustard beetle larvae (Phaedon cochleariae), as long as the leaves are still moist.

After the desired time, the destruction in % is determined. 100% means that all the beetle larvae have been killed; 0% means that none of the beetle larvae have been killed.

In this test the compounds from Preparation Examples 1 and 2 exhibit a degree of mortality of 65% at a concentration of active compound of 0.1%.
